A security audit reveals that a legacy application running on a Windows 10 workstation transmits sensitive data over an unencrypted protocol. The application is critical for business operations and cannot be updated or replaced. The workstation is located in a secured server room with restricted physical access. Which of the following would BEST mitigate the risk of data interception for this legacy application?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Implement an IPsec policy on the workstation to encrypt all network traffic.
IPsec provides end-to-end encryption at the network layer, securing all communications from the workstation regardless of application protocol. It can be enforced via Group Policy or local settings.
B
Distractor review
Install a VPN client on the workstation and connect to a corporate VPN server.
A VPN only encrypts traffic that goes through the VPN tunnel. If the legacy application uses a non-VPN route or the VPN disconnects, data could be exposed. Also, it may not encrypt local network traffic.
C
Distractor review
Change the application configuration to use HTTPS for communication.
The scenario explicitly states the application cannot be updated or replaced. Modifying its protocol is not an option.
D
Distractor review
Place the workstation on an isolated VLAN that has no access to external networks.
VLAN isolation can reduce the attack surface, but it does not encrypt the data still transmitted over the network. Data on the isolated VLAN could still be intercepted by an attacker with access to that VLAN.
Common exam trap
Common exam trap: an active trunk can still block the VLAN you need
A trunk being up does not prove every VLAN is crossing it. Check allowed VLAN lists, native VLAN mismatch, VLAN existence and access-port assignment.
Technical deep dive
How to think about this question
VLAN questions usually combine access-port and trunking clues. The key is to identify whether the issue is local to one switchport, caused by the trunk, or caused by the VLAN not existing where it needs to exist.
KKey Concepts to Remember
- Access ports place end devices into a single VLAN.
- Trunk ports carry multiple VLANs between switches.
- Allowed VLAN lists decide which VLANs can cross a trunk.
- Native VLAN mismatch can create confusing symptoms.
TExam Day Tips
- Use show vlan brief to verify access VLANs.
- Use show interfaces trunk to verify trunk state and allowed VLANs.
- Do not treat every same-VLAN issue as a routing problem.

Question 1
A user reports intermittent network connectivity on a desktop computer. The technician observes that the Ethernet link light on the NIC turns off for a few seconds and then turns back on. The cable passes a wiremap test, the switch port is verified good with another device, and the NIC driver is updated. The issue occurs more frequently when the computer's case fan runs at high speed. Which of the following is the MOST likely cause?
Question 2
A workstation is unable to connect to the internet. The technician runs the 'ipconfig' command and sees the IPv4 address is 169.254.15.200 with a subnet mask of 255.255.0.0. The workstation can ping other devices on the local subnet but cannot ping the default gateway or any external addresses. Which TWO actions should the technician take to resolve this issue? (Select two.)
Question 3
A workstation is connected to a managed switch. It obtains a valid IP address (192.168.10.50) from the DHCP server, but it cannot ping the default gateway (192.168.10.1). The link light on both the workstation NIC and the switch port are solid green. Other workstations on the same switch CAN ping the default gateway successfully. The technician accesses the switch management interface and finds that the workstation's port is configured as an access port on VLAN 10. The default gateway is located on VLAN 20. An inter-VLAN router is configured but not explicitly allowing VLAN 10 access to VLAN 20. Which of the following is the MOST likely cause of the problem?
Question 4
A company develops a web application that relies on a custom library available only for a specific Linux distribution. They want to deploy the application in the cloud with minimal administrative overhead, but they need full control over the software stack, including the ability to install the custom library and configure the web server. Which cloud service model BEST meets these requirements?
Question 5
A company has a legacy virtual machine running on a deprecated hypervisor (Hyper-V). They want to migrate this VM to a new hypervisor (VMware vSphere) hosted in a private cloud while preserving the VM's configuration, installed applications, and data. The migration must be performed with minimal downtime. Which of the following methods is MOST appropriate?
Question 6
A company hosts a critical database on a virtual machine in a public cloud. The database requires persistent storage that must be retained even if the VM is terminated. The storage must also be accessible from multiple VMs simultaneously for a future high-availability configuration. Which type of cloud storage BEST meets these requirements?
FAQ
Questions learners often ask
What does this 220-1101 question test?
Access ports place end devices into a single VLAN.
What is the correct answer to this question?
The correct answer is: Implement an IPsec policy on the workstation to encrypt all network traffic. — IPsec (Internet Protocol Security) can be configured on the workstation to encrypt all outbound traffic at the network layer, protecting data in transit without modifying the application. A VPN client may be an alternative but typically only encrypts traffic to the VPN gateway, not all network traffic, and may not be persistent. Placing the workstation on an isolated VLAN reduces exposure but does not encrypt the data. Modifying the application is not possible per the scenario.
